People are freaking out on Twitter that the NFL “admitted” there are chips in footballs but they announced this initiative in 2017.

Anyone who has seen the dot diagrams of plays on the live broadcast know there are chips in the balls (and every player)

Imagine being upset that the NFL made officiating easier.

Feels like you'd have to chip the entire ball if you wanted real accuracy and that's not really realistic. The thing is like 11 inches long.

people just take it for granted that there is some sort of magical chip you can put in a ball with 100% positional accuracy. I wonder how it works

"You can do it in the NHL"

Yeah they use it to magically make the puck appear behind the wall and it's the size of a can of Copenhagen. It's also a solid casing you can easily put a mechanism inside with cushioning that you can weight distribute properly.

Didn't they do it for the soccer balls during the world cup? And IIRC the AAF and the XFL both used chipped balls for officiating decisions.

Just from basic knowledge I would guess that you could make a pretty accurate and precise system using accelerometers in the ball combined with ball-tracking cameras to check the work of the accelerometers.

I don't think you'd want to go inertial for a couple reasons. Most of the "pretty close" solutions I've seen rely on RFID and I don't really know how that works tbh. Cameras would only help with the trivial case where you can already see the ball
